This is excellent advise, IMO. The only thing I'd like to add is one reason to bet the flop here is that sb would think you must have something to be betting into a zero dollar side pot and if you can get him to fold this already large pot for the price of one small bet, that's +++EV. And if he calls you then will almost always have the option of seeing two more cards for the price of that one small bet. Win, win for you.
